Cleans very well
Gives white WC, for now and then
100% ineffective. A waste of time and money. No product action in toilets.
Great for cleaning
Great for heavy soiling
March of god's thunder
Effective but super-expensive
Great buy. Works well but toilets are very clean
Plaster always perfect.
Please don't breathe in the powder dust, it's terrible. Even if I empty the bag at the very bottom near the water, there is very fine powder dust. I don't like that. I prefer tabs.
